03 Performance and Compositing Considerations
-
GPU Acceleration CSS filters (blur, drop-shadow, brightness, contrast) trigger GPU compositing, which means the browser creates a separate texture layer for the filtered element. This is fast for static elements but expensive for animations, animating filter: blur() on scroll can cause jank on mobile devices. Use will-change: filter to hint at upcoming animations.
-
Filter vs Mix-Blend-Mode CSS filter modifies the element itself, while mix-blend-mode controls how the element composites with its background. Use filters for image adjustments (brightness, contrast, grayscale) and blend modes for creative overlays (multiply, screen, overlay). backdrop-filter applies filters to the area behind an element, perfect for glassmorphism effects.
